Nystatin, a topical oral antifungal, is usually the preferred choice in pregnancy. It works by acting locally in the mouth and is minimally absorbed into the bloodstream, making it a safer option for pregnant women with oral thrush. Other antifungals, such as clotrimazole lozenges, may be considered if nystatin is not effective or tolerated, but both should only be used under medical supervision. Meet our dental team
